JK660 is an All-In-One DTH drilling rig, which brings you moreautomation, higher working efficiency, better reliability andsimpler operation. The integration of drilling rig and air compres-

sor, the design has many advantages like facilitating air compres-sor transport and management on mining site,retaining more air energy and requiring less manpower. The equipped high-perfor-mance hydraulic dust collecting system meets the latest environ-mental protection regulations and it's a reliable solution to realize the modern green mining.

Rotation unit system

The gearbox has large gear reductionratio, high torque transmission efficiency ,runs smoothly, lowered failure rate and with less routine maintenance cost. It also reduces pipe-stuck situations in unconsolidated formations and has a higher hole completion rate.

Polymer liner plates are high resistant to abrasion, no need lubricating grease so the maintenance is easy and convenient.

Manganese steel-made sliding rail of the feed boom has high strength structure and superior resistance to wear.

The original high-output Atlas Copco air compressor delivers pressure of 17bar and FAD of 17m3/min.Powerful and reliable, it suits rock formations of various hardness and offers high penetration rate with ease.
